CCTV images of a man police would like to speak to after a group of youths were threatened with a knife have been released.
A member of the public reported to police that a youth had brandished a knife at a group of youths in Church Square, St Helens, on January 17 at around noon.
The youth then ran through the nearby St Mary’s shopping arcade.
Sergeant Neil Birkett said: “While no-one was injured during this incident, someone has brandished a knife in the middle of the day, in a busy shopping area and I’m sure the local community would agree that this offender needs to be brought to justice.
“We believe this to be an isolated incident - we have examined CCTV and carried out extensive enquiries in the area. I would appeal to anyone who was in the area at the time, or anyone who has any information about this incident to get in contact.”
Anyone with any information about this incident is asked to contact 0151 777 1577, 101 or Crimestoppers anonymously on 0800 555 111.
